Well you can tow 5100 lbs. Tongue is about 650. Roo weight 4300..
You will be at max IMO..and probably over if you load the yukon with passangers...
Your best way to figure what you can tow is weight the yukon empty. Then weight the yukon with all passengers and full fuel and cargo..
Post back with those #'s and the axle rating on the door jam.. That will give you an idea of what you can really tow...
But in reality your GCVW rating is 11k. Yukon 7200 plus 4300 empty roo = 11500 lbs..
Your over...
As they say in NJ... forgetaboutit!!!!
Just my opinion...
